Best Natural Gas Heaters

Infrared heaters are popular at home and in the workplace, thanks to their efficiency, quietness, and ease of operation. If you need a larger space, such as a warehouse, an auditorium or a large garage to be heated, you’ll probably want to find the best high-intensity infrared space heater for the job. Having looked at a good number of the options currently available on the market, I have to say that my favorite is the HeatStar F180628.

HeatStar F180628When comparing different high-intensity heaters, you are looking at the way energy is generated from the passing of air and gas through a porous matrix refractory material, in order to ignite it. This surface can reach extremely high temperatures and emits a highly concentrated dose of radiation in the direction the heater is facing.

As such, you need to ensure that the heater you buy is safe and that the brand in question has a good safety record. Furthermore, you need to bear in mind that these heaters are typically unvented – this makes it essential that you choose the right heater for the right space – some heaters in unventilated spaces will eventually cause the buildup of dangerous gases.

On top of these things, there are a number of other considerations you will need to deal with, such as ease of installation, size, weight and so on. In general terms, I think the F180628 is heater most likely to do the best job for most people’s needs.

So What Is the F180628 Like?

This is a powerful heater, with a maximum output of 120,000 BTU, designed to be effective over an area of 3,000 square feet. A blower is included with the heater, which requires electrical power to function. In terms of fuel consumption, it will go through on average of 5.57 gallons of natural gas per hour. It measures 82.5 x 21.5 x 11 inches. There is no thermostat included as standard, but this is provided as an option.

What’s So Good About It?

This high-intensity heater is perfect for use in wider spaces, such as barns, warehouses, and factories. It’s quiet when in operation, which is important in working environments which may already suffer from high levels of machinery noise, and in which clear communication is necessary. HeatStar is a trusted brand which makes dependable, long-lasting and easy-to-maintain products.

What Could Be Better about It?

This heater doesn’t come with an oxygen depletion sensor, so you’ll possibly need to monitor the air quality and carbon monoxide levels independently. As such, it’s suitable mostly for workspaces which are adequately ventilated and not closed off. In addition to this, the machine doesn’t have a remote control function, which could end up having an effect on exactly where it is positioned.

Why This is Probably the Heater You’re Looking for

In terms of pure functionality, it does a great job of heating large spaces, it’s easy to use and maintain, plus it’s almost unnoticeable in terms of the sound it makes – that’s why I recommend it.

Runner-Up #1 – HeatStar F191828 High-Intensity Gas Heater

HeatStar High-Intensity F191828 Gas HeaterAnother high-intensity infrared heater from HeatStar, the F191828 is, put simply, pretty much a smaller version of the F180626. This heater has a slightly lower output of 100,000 BTU, along with lower fuel consumption of 4.62 gallons of natural gas per hour. It measures 60.5 x 21.5 x 11 inches and, like it’s a larger sibling, has the option of a thermostat.

The F191828 is basically the same as the F180628, but smaller – hence its high rating. It has everything going for it that the larger model does, but it’s more suited to smaller spaces. Using too large a heater in your space could lead to an unnecessary, costly, wastage of fuel.

Runner-Up #2 – Mr. Heater MH40NG Natural Gas Heater

Mr. Heater MH40NG Natural Gas HeaterThis heater is designed for spaces of up to 1,000 square feet, with ceilings typically as high as 15 feet. Its maximum heat energy output is 40,000 BTU. Unlike the two previous models I mentioned, this heater does come with a thermostat. It’s much smaller, measuring 35.5 x 12.5 x 21 inches and weighing only 28.2 pounds.

This heater, while still considered to be a space heater, is suited to smaller spaces such as garages. The thermostat is a great inclusion, and this model is also popular due to its ease of maintenance. It needs to be kept a safe distance from combustibles, however, so you’ll need to bear that in mind before purchasing.

Runner-Up #3 – Sunstar SGM10 LP Gas Infrared Ceramic Heater

Sunstar SGM10 LP Gas Infrared Ceramic HeaterThis Sunstar heater is back at the higher end of the scale, with a maximum output of 104,000 BTU. It can be angle-mounted and comes with reflector extensions. Unsurprisingly, it’s one of the heavier infrared space heaters, weighing 74 pounds.

This heater is most suitable for shops, warehouses, service areas and so on, especially in rural areas as it can be operated entirely without electricity. The main attraction, in my view, is the possibility of angling the heater, plus using the reflector extensions to get heat to awkward or obscured areas. If you find certain areas of your workspace to be much colder than others, this space heater could be your ideal solution.

A Summary

Choosing a heater for your workspace is a decision that needs to be made carefully. By going with a natural gas-powered infrared space heater, you are automatically getting certain benefits such as low noise output and fuel efficiency. At the same time, you are taking on potential hazards, such as deoxygenation of the working space. That’s why it’s important to choose the right space heater for your space.

Obviously, the main consideration in making this choice will be the capacity you need. There is no point in buying a huge heater for a relatively small work area. That said, the HeatStar F180628 is my favorite, along with its sister, the F191828, thanks mainly to their reliability plus ease of operation and maintenance.
